It may be an old superstition but Green on a bike tends to be bad luck. I was advised of this about two weeks after I took delivery of my Green 1975 Honda CB550. I contributed to this superstition a few weeks later when I hit something slippery on an exit ramp and ran off the road. All was fine until I hit a drainage ditch that I couldn't see because it was overgrown with grass. Messed up the bike and my chin. (open face helmet with plastic face shield) The only lucky thing was I was on my way home from looking at my new 1975 RED Goldwing which had just came in the day before. Picked it up two days later!
Just an observation...
